SINE-TRAP.

Specification of Letters Patent.

Application filed. April 16, 1908. Serial No. 427,464.

To all where it may concern.'

Be it known that I, THOMAS E. DoYLE, of Milwaukee, YVisconsin, haveinvented a Sink- Trap, of which the following is a specification.

This invention relates to water-traps Y trap and enables all that partvof the trap except the horizontal limb to be set in the wall; a readilydisconnectible joint in said limb; and a second outlet extending fromthe upper bend of the tra within the wall to a point outside the wal Myinvention can best be'understood from a consideration ofthe accompanyingdrawing showing the most approved form thereof, taken in connection withthe followingr description thereof. In this drawing, the trap is shownin longitudinal section in position in the wall, having a sink or basinb connected thereto.

rl`he trap is made in two parts, designated c and d respectively, thefirst bein(T connected to the drain-outlet e of the basin by a union forin any other approved manner, and being connected to the second sectionby a union g, which lies as close as possible to the face of the wall a,the hole in the latter being, if desired, covered by a canopy h. Thesection c corresponds to a art of t ie first bendv of the trap, theremain er of said bend beinor completed by the limb i ofthe section d,which as shown is upwardly bent, forming the usual U-shaped water-seal.At the u per end of the limb i is an air-chamber w ich has an outlet c.connnunicating wit throu h a vent-pipe m; and a downwardly exten inglimb 'n communicates with the house-drain o, to which it is secured by aunion or other form of joint p.

The important element of this invention which I claimias new consists ofthe sideoutlet g at the top of th'e air-chamber y', which extends to apoint on the fece of the -wall and is covered by a scre.\\'plug 1'.

Through this butlet the trap may be cleaned, especially the limb n 'andair-chamber j the outer air' thereof, of any obstructing matters asremoving the plug r a wire or other c eaui. device.can -readily beinserted into thr trapt and the obstruction removed without in any?l waydisturbing the settings of the trap orthe wall. Ordinarily there lwillalso be another? cleaning outlet s at the bend of the horizontal limb c,which is closed by a screw-plug t. Having thus described my invention,what I claim as new and desire to secure by Letters Patent is: v

l. A sink or trap of the S-pattefn havin@ a main body adaptedl to liewithin a wall, vthe lower bend thereof being prolonged inte a;

horizontal limb extending outside 'the wall- Patenfed June 2919ogg` to apoint beneath the drain-outlet Qf a sink.-

or basin and ada ted to be connectedlthereto, said part wit iin the wallcomprising an upward bend, an air-chamber at the top of said bend and adownward bend adapted to a be connected with a drain-pipe, a tubularcleaning-outlet extending from said alrehamber, to the face ofthe Wall,and a coveringfor the end of said cleaning-outlet. e 2. The combinationof a wall, a trap having a main body including an air-chamber thereinlying within said wall and having a long horizontal limb constituting aWaterseal and extending to a point outside the wall and from thereextending upwardly, a sink or basin having a drain-outlet directlyconnected with said horizontal limb, a tubular cleaning outlet extendingfrom thea1rv chamber of said trap to the face of and a plug closing saidoutlet.

3. In combination with a wall and a basin, a trap of the S-type havingthe main body said wall,

the lower bend thereof prolonged 'to form a horizontal limb whichextends outside said.

.thereof lying within said wall and having' l wall, is turned upwardlyat the end and connected with the drain-outlet of sa'id basin, saidtraphaving further an -air-cham` r at the to of its upper bend and adownwardly exten ing limb extending from said air-chamber, to the faceofsaid wall, and a screw-plug4 closing' said' Titnesses GEO.
